So, if we’re about to see it doesn’t that mean that it actually exploded about 3000 years ago?

OK so this one seems to happen any moment now.
Still doubt it’ll be noticeable.
From wikipedia: „Even when at peak magnitude of 2.5, this recurrent nova is dimmer than about 120 brightest stars in the night sky.“
Once in a lifetime? Hopefully not because it is a life ending event.
But how do they know it will „explode“? I only have a passing knowledge of this kind of stuff but isn’t predicting a supernova almost impossible given our current understanding?
Soon on astronomical and cosmological scales could mean „tomorrow“ or it could mean „500 years from now“.
This title and article do a terrible job of explaining anything at all, so for those confused about when this will occur in the context of 3000 light years:
Blaze Star is a recurrant nova that flares every 80 years or so. Last observed in 1946. It is this repeated activity that allows astronomers to predict that we’ll see it again soon.
The prediction for the next flare is between now and early 2027. And it is likely to go unnoticed by most people.

“Only explodes once every 80 years” how does that work?
